Question

A transcription unit is defined by three structural regions. Which of the following correctly lists these three regions in their proper order from 5' to 3' on the coding strand?

विकल्प

• Promoter, Terminator, Structural Gene

• Structural Gene, Promoter, Terminator

• Promoter, Structural Gene, Terminator

• Terminator, Structural Gene, Promoter

Answer 1

A transcription unit consists of three essential components arranged sequentially: the Promoter at the 5' end (upstream), the Structural Gene in the middle carrying the information to be transcribed, and the Terminator at the 3' end (downstream). This organization ensures proper initiation, transcription, and termination of the RNA synthesis process.
